The original synapsid skull structure contains one temporal opening behind the orbitals, in a fairly low position on the skull (lower right in this image). This opening might have assisted in containing the jaw muscles of these organisms which could have increased their biting strength.

Mammal

Mammals (from Latin mamma, 'breast') are a group of vertebrates constituting the class Mammalia, characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones.

Quadrupedalism

The zebra is a quadruped.

Quadrupedalism is a form of terrestrial locomotion where a tetrapod (as well as mantises, who primarily walk in this way) animal uses all four limbs (legs) to bear weight, walk, and run.
